Ok... On our recent cruises, we've come across something we considered a bit odd. Not sure this has been discussed here before. Two times in our last four cruises there has been a male passenger (different guy) walking around the ship in his bathrobe. I'm not talking about walking to/from the pool area or spa. Nope, I mean he did it in the 24 hour cafe, the buffet area, library, Internet cafe, etc. He wasn't doing anyone harm but it did get my attention because it seemed a bit too casual. Yes, it's a vacation and everyone does things differently but I wouldn't walk into Starbucks in my bathrobe on land and asked myself what makes this ok to do so at sea?  I'm still not sure how I feel about this so wanted to see if anyone had opinions about it?
